I think giving Reyna to Sheydos is a good movement, I prefer him rather than Chronicle, I feel Sheydos has more firepower and I think is better giving Sova to Redgar and Chronicle plays Sage, I dont like having the IGL on a Sage in Icebox.
Yeah, Chronicle is definetly nuts on Reyna, but I think Sheydos can do even better, the problem I find on Sheydos is that he usually chokes on crucial rounds/games and with Reyna you gotta be fearless.
